You can see divine vengeance going on in this story because of what happens to the Adams twins at the end.

The early parts of this story show us that one of the Adams twins is clearly guilty of murder. The problem is that this twin is going to escape punishment from human beings because of the fact that the two of them are identical. Witnesses have no idea which of them committed the crime and so neither will be found guilty.

But (you can argue) God is not going to allow this to happen. After the twins escape human justice, one of them ends up being killed by a bus. We are not told exactly how it happens, but that doesn't matter. The twins escaped human justice but, you can argue, they could not escape God's revenge, His divine vengeance.

Divine vengeance is the main essence of the uncanny classic, "The Case for the Defence", by Graham Greene.

Initially, in the story, Greene presents forth that at least one of the Adams are certainly the murderers. This can be understood clearly by the number of evidences (witnesses), and the manner of writing of Greene. The scene yet plays loopholes and ultimately both the Adams escape without any of them held guilty. This is certainly against the “DIVINE JUSTICE”. It is obvious that when things get beyond the hands of we mortals, the spiritual Lord does justice. After the twins escape human justice, one of them ends up being killed by a bus. This is not elaborate to any great extent as it gives the story a sinister appeal. Hence, to answer your question, this is a clear cut example of divine vengeance.
